摘　　要：Solid phase synthesis and formation mechanism of SrB6powder are studied systematically i n this paper.X-ray diffraction and scanni ng electron microscopy analysis show that interaction in the SrCO3-B4C-C system intended to strontium hexaboride formation belongs to solid p hase processes and passes through the stages of transit ion phases Sr3B2O6,SrB2O4 formation etc.The optimal technolo gy of strontium hexaboride synthesis i s holding time of 2.5h at 1400℃under 10-2Pa vacuums.The shape of B4C powder decide that of SrB6.Solid phase synthesis and formation mechanism of SrB6 powder are studied systematically in this paper. X-ray diffraction and scanning electron microscopy analysis show that interaction in the SrCO3-B4C-C system intended to strontium hexaboride formation belongs to solid phase processes and passes through the stages of transition phases Sr3B2O6, SrB2O4 formation etc. The optimal technology of strontium hexaboride synthesis is holding time of 2.5 h at 1400 degreesC under 10(-2) Pa vacuums. The shape of B4C powder decide that of SrB6.
